To all whom it may concern:

Be it known that I, EMIL VON DUNGERN,

residing at Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Modified Milk and Process of Obtaining Same, of which the following is a specification.

Endeavors have been made of late to render cows and goats milk more suitable for the nourishment of children and invalids. An

essential objection to such milk, however, has It consists in not hitherto been overcome. the fact that cows and goats milk produce with gastric juice a coarse coagulum, which resists the penetration of the digesting juice much more effectively than does the fine flaky solid matter of human milk. The coarse casein I also been made to overcome it by removing the precipitated casein or by rendering the casein digestible by adding pancreatin to the milk. The first method has the disadvantage that these additions are badly borne by children during prolonged administration, and the second that the removal of the casein takes the greatest part of the nourishment in the milk, while the artificial digestion necessitates conditions which render its general application out of the question.

I have found that the injurious coagulation in the form of lumps of the casein of cows and goats milk in the stomach may be av gled in a simple manner. c

To the milk, which may be boiled, is added some rennet ferment. After a few minutes a comp'a'ct'coagulum is formed. This curdis,

then shaken and beaten, by which meaifi the preparations hitherto employed.

Having now described my invention, What I claim is 1. The herein-described process of treating cows or goatis milk to render it more digestible by infants and invalids, which consists in adding a rennet ferment to the milk, whereby the same is separated into whey and a casein coagulate, and then mechanically breaking up said coagulate into fine flakes so that only fine flakes remain in suspension in the whey, substantially as set forth.

2. As a new product, cows or goats milk, containing whey, and a casein coagulate in fine flakes held in suspension in said Whey, said milk resembling the original milk in composition, taste and appearance, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
